WordPress 3.3 custom post type with /%postname%/ permastruct?

This isn’t easily done in WP 3.3 unless you trick the rewrite rules to be in the correct spot and make wp_rewrite think verbose rules are being used in the front end. The class below works.

class Test_Post_Type {
    const POST_TYPE = 'test';

    public static function init() {
        global $wp_rewrite;

        $post_type_obj = register_post_type( self::POST_TYPE, array(
            'labels' => array(
                'name' => __( 'Tests' ),
                'singular_name' => __( 'Test' ),
                'add_new' => __( 'Add New' ),
                'add_new_item' => __( 'Add New Test' ),
                'edit_item' => __( 'Edit Test' ),
                'new_item' => __( 'New Test' ),
                'all_items' => __( 'All Tests' ),
                'view_item' => __( 'View Test' ),
                'search_items' => __( 'Search Tests' ),
                'not_found' => __( 'No Tests found' ),
                'not_found_in_trash' => __( 'No Tests found in Trash' ),
                'menu_name' => __( 'Tests' )
            ),
            'publicly_queryable' => true,
            'exclude_from_search' => true,
            'hierarchical' => false,
            'public' => true,
            'rewrite' => false,
            'has_archive' => true,
            'supports' => array( 'title', 'editor', 'thumbnail', 'test_source' ),
            'taxonomies' => array( 'category', 'post_tag' ),
        ) );

        $post_type_obj = get_post_type_object(self::POST_TYPE);

        //register the rewrite tag for permalink building
        $wp_rewrite->add_rewrite_tag( '%' . $post_type_obj->query_var . '%', '([^/]+)', $post_type_obj->query_var . '=' );

        //we have to add the permastruct here in order to build the permalink, otherwise we'll need to filter the post_type link
        add_permastruct(self::POST_TYPE, '%' . $post_type_obj->query_var . '%/', false );

        //add a filter to remove the permastructs generated above
        add_filter(self::POST_TYPE . '_rewrite_rules', array(__CLASS__, '_remove_default_rules')); 

        //now we add a filter to put the generated rewrite rules in the correct spot
        add_action('generate_rewrite_rules', array(__CLASS__, '_filter_rewrite_rules'));

        if(!is_admin()) {
            //we need verbose_page_rules to be on on the front end in order for pages to be process properly
            $wp_rewrite->use_verbose_page_rules = true;
        }
    }

    /**
     * Filter to remove the rules for this post type when they're automatically generated due to the permastruct registration
     * @param type $rules
     * @return type 
     */
    public static function _remove_default_rules($rules) {
        return array();
    }

    /**
     * Filters the rules at the end to add back the ones for this post type at the bottom
     * @param WP_Rewrite $wp_rewrite 
     */
    public static function _filter_rewrite_rules($wp_rewrite) {
        $post_type_obj = get_post_type_object(self::POST_TYPE);
        $my_rules = $wp_rewrite->generate_rewrite_rules('%' . $post_type_obj->query_var . '%', EP_NONE);
        $wp_rewrite->rules += $my_rules;
    }

}

add_action( 'init', array( 'Test_Post_Type', 'init' ) );
